Anticiation, frustration, whichever

Ok, so after finding out that Walmart online carries far more than their stores do (I know, kinda obvious, right?) I was able to order all but 1 part for my MythTv setup using the gift card Mom sent. (After discussion, we decided that was the best way to handle Grandma's bequest) You know the worst part about ordering online?  Waiting.  Never really noticed it before, and I've ordered quite a few things like this, but this time it's driving me nuts.  I think it has more to do with wanting to get started on the MythTv build than the tv.  I've done all I can 'til the parts get here. (On that note, the fact that the dvi to hdmi cable is running 3 days later than everything else worries me, but not as much as the fact that Walmart says that the cat 5 cable has shipped, but FedEx hasn't received it yet.)  Yes I am checking every 5 minutes.  Yes I do know that will make it worse. Knowing those facts does nothing at all to help me alter the behavior, it just makes the behavior that much more frustrating.  Grrr.
